Do catamarans have bathrooms?

Yes, catamarans have bathrooms, and on a crewed charter catamaran every guest cabin typically gets its own private ensuite. Boats in the 45 to 55 foot range usually run four cabins and four heads, each with an electric freshwater toilet, a sink, and a shower. Newer models like the Lagoon 51 or Leopard 50 add separate glass-door shower stalls, so nobody showers over the toilet. Hot water is standard. Watermakers on crewed boats produce hundreds of gallons a day, which means real showers, not rationing. Day-sail and bareboat cats are more variable; some share one head between two cabins. Ask for the layout sheet before booking, or read what to expect on a yacht charter first.
